WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 609,798, dated August30, 1898. Application led January 18, 189'?. Serial No: 619,657. (Nomodel.)

To all whom it may con/cern.'

Be it known that I, CLARENCE MCCLELLAN EVELETH, a citizen of the UnitedStates, residing at Plymouth, in the county of Grafton and State of NewHampshire, have invented a new and useful Door Attachment,of which thefollowing is a specification.

My invention relates to weather-strip attachments particularly adaptedfor doors, and has for its object to provide a simple, compact, andeflicient construction and arrangement of parts mounted upon andinclosed within a frame forming'a part of the attachment and adapted asan entirety to be countersunk or fitted in a longitudinal groove or kerfformed in the edge of a door.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure l is a longitudinal sectional View of anattachment constructed in accordance with my invention applied in theoperative position to the loweredge of a door. Fig. 2 is a perspectiveview of the cas- Fig. 3 is an end view of the weather-strip arranged-inits operative position. Fig. 4 is a detail view, partly in section, ofthe connection 1between the push-rod and the depressing-lever.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

The casing or frame in which the operating parts of the attachmentembodying my invention are mounted is parallel-sided and consists ofparallel side plates l, preferably cut away or scrolled to reduce theweight thereof, and spacing-blocks 2, interposed at terminal andintermediate points between the side plates to maintain them in theirproper relative positions, said side plates being provided at theirlower edges with outwardly-turned securing-ears 3, through which mayextend screws for holding the attachment in the longitudinal kerf orgroove formed in the edge of a door. Obviously this kerf or groove inthe door must be of such a width and depth as to receive and snugly fitthe frame or casing to avoid rattling or displacement when the door isjarred.

Snugly fitted between and guided vertically by the inner or opposingfaces of the side plates 1 is a drop strip or bar 4, terminating flushwith the ends of the side plates l, and hence hush with the side edgesof the door to which the attachment is applied, the length of the frameor casing of the attachment being equal with that of the edge of thedoor in which it is countersunk. Lifting or return springs 7 are securedat their outer ends to the drop strip or barnear its terminals and areengaged at their inner ends with studs or cross-pins S located betweenthe planes of the side plates and supported in xed positions thereby,and the upward movement of the drop-bar when released for actuation bythe return-springs 7 is limited by the terminal spacing-blocks 2, underwhich the extremities of said drop-bar extend, as shown in Fig. l.Endwise displacement of the drop-bar is prevented without the use ofauxiliary guides or equivalent means by coiling the extremity of one ofthe springs 7 around the stud or cross-pin 8 upon which it has abearing; but in order that the drop-bar may be free to tilt to occupy aposition with one extremity lower than the other, whereby it mayproperly bear upon an inclined surface or a surface disposed slightlyout of parallelism with the lower edge of the door, the inner end of theother lifting-spring 7 merely extends over and bears upon the upper sideof its supporting stud or cross in S. p In order that inequalities inthe surface of the door or sill may not interfere with the properbearing of `the strip, and hence the efficient exclusion of draft, thelower edge of the drop-bar is preferably provided with a yielding orcompressible bearingstrip o r extension 5 of rubber, felt,`or equivalentmaterial, having a tongue or lip G tted in a groove in the lower edge ofthe drop-bar, as shown in Fig. 3 and in dott-ed lines in Fig. 1.V

Mounted between the planes of the side plates l, above the upper edge ofthe drop.- bar, is abelldcrank lever 9, having a long arm to bearterminally upon the upper edge of the drop-bar at an intermediate pointapproxithe drop-bar and having a short arm extending upwardly andprovided with a seat, in which is loosely fitted a thimble 10, saidthimmately midway between the extremities of ble being freeto rock in avertical plane in the seat of the lever and also to move axially y orallow swinging movement of the lever in- Y the thimble and bearingterminallT upon said collar and flange is a push-rod-operatin g orreturn spring 13, held from displacement in one direction with relationto the thimble by means of a pin or equivalent device arthimble andobviously held from displacement in the opposite direction by thespring, while capable of independent sliding movement through thethimble in opposition to the tension of said spring. Thus as the door isclosed the extremity of the push-rod comes into contact with theadjustable stop 15 and forcesl the push-rod inwardly or toward the freeedge of the door, thus applying pressure to the short arm of thedepressing-lever 9 and causing it to depress the drop-bar against thetension of its supporting-springs, 7. As the parts are thus operated thethimble 10 is allowed to rock in its seat in the depressinglever toavoid straining the push-rod transversely and to maintain a suitablebearing for the contiguous end of the spring 13,and should the drop-baror the elastic strip thereon meet an obstruction of any considerablesize the spring 13 will yield to avoid straining the parts. Said spring13 by its pressure through the thimble upon the short arm of thedepressing-lever holds the drop-bar with its elastic. strip in yieldingcontact with the sill or the surface of the floor below the lower edgeof the door. Obviously a sill may be omitted where a strip of this classis used and thus an obstacle common in doorways may be avoided. Foroutside house-doors, however, it is preferable to use a sill to serve asa water-shed, as in the ordinary practice.

Various changes in the form, proportion,

and the minor details of construction may be resorted to withoutdeparting from the spirit or sacriiicing any of the advantages of thisinvention.

Having described my invention, what I claim is v 1. A weather-striphaving a drop-bar, return-springs attached to said bar and engaged withixed supporting-pins, the extremity of one of said springs being coiledaround its supporting-pin to hold the bar from endwise displacement,vand the extremity of the other spring having a sliding bearing upon itssupporting-pin to allow tilting movement of the A bar, and depressingdevices having means for applying downward pressure to the drop-bar atan intermediate point, substantially as specified. ranged therein beyondthe extremity of said 2. The herein-described weather-strip attachmentfor doors, the same comprising a parallel-sided frame or casingconsisting of parallel side plates and interposed terminal j andintermediate spacing-blocks, a drop-bar fitted snugly between and guidedfor vertical movement by the opposing faces of said side plates andterminally flush with the ends of said side plates, lifting-springsattached at their outer ends to the drop-bar and bearing at their innerends upon cross-pins connecting the side plates of the frame, one ofsaid springs being engaged with its cross-pin to prevent endwisedisplacement of the drop-bar, and the upward movement of the drop-barbeing limited by the said terminal spacing-blocks, a depressing-lever,and a push-bar having a yielding connection with the depressing-lever,

to apply pressure therethrough to the dropv bar, all being mounted upon,and between the planes of the opposing faces of, the side plates of theframe, Jforsimultaneous insertion therewith into a longitudinal kerl orgroove of a door edge, substantially as specilied.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of twowitnesses.
